help Phanteks Eclipse P300 FAQ
What's the difference between the Phanteks Eclipse P300 and the P300A?
The P300A is the airflow-focused variant with a perforated mesh front panel for better cooling, while the original P300 has a more solid front with side ventilation. Both share the same chassis footprint and tempered glass side panel.
How many fans are pre-installed in the Phanteks Eclipse P300?
The Eclipse P300 typically ships with a single 120 mm rear exhaust fan, leaving the front intake mounts for user-supplied fans. The P300A variant usually includes additional pre-installed fans.
Will a 240 mm AIO like the Corsair H100i fit in the Phanteks Eclipse P300?
Yes, the P300 supports up to a 280 mm radiator in the front and a 240 mm radiator on top. Front-mount radiator installs may require removing the front drive cage to clear larger cards.
What's the GPU clearance for the Phanteks Eclipse P300?
The Eclipse P300 supports graphics cards up to about 370 mm with the front HDD cage removed — enough for an RTX 4070 / 4070 Ti but tight for the longest RTX 4090 models. With the cage installed, the clearance drops meaningfully.
